The anorexiaFT data set that comes with the cg package is in groupcolumns format for the
prepareCGPairedDifferenceData call. Each column represents a group, and each row represents an individual patient, or experimental unit. Each observation in a row that spans the two group columns are paired individual response or outcome values.

The purpose of the study was to evaluate effects of multiple treatments on weight as a marker for anorexia, and to compare their relative effectiveness.
